MILLROCK ACQUIRES OPTION ON LA NAVIDAD GOLD

PROJECT AND MAKES JOINT VENTURE AGREEMENT WITH

CENTERRA GOLD, SONORA STATE, MEXICO

VANCOUVER, BRITISH COLUMBIA, June 13th, 2017 - Millrock Resources Inc. (TSX-V:

MRO) ("Millrock") announces it has entered an option agreement to purchase the La Navidad

gold project from a private Mexico firm, Western Mining S.A. de C.V (“Western”). The

concessions under option are adjacent to surrounding concessions already held by Millrock.

Together the district-scale land package covers more than 25,000 hectares in the Magdalena di

Kino Mining area of Sonora State, Mexico. Simultaneously with the purchase agreement,

Millrock has entered an option to joint venture agreement with Centerra Gold Inc. (“Centerra”).

Centerra will fund initial exploration on the project. Work is scheduled to begin immediately.

Gregory A. Beischer, President & CEO commented: “There is at least one known, moderately-

dipping, near-surface structure that is reported to host gold over significant intervals. Through

drilling, we look forward to verifying the previously-reported historic results and expanding the

limits of the reported mineralization. Pursuing this project has been made possible through our

ongoing partnership with Centerra”.

Gold mineralization at La Navidad is hosted by low-angle faults related to the Magdalena

Metamorphic Core Complex. The zone of faults has been traced over a 2.2 kilometer distance

and ranges from 300 to 600 meters in apparent, surface width. Sub-parallel shears that trend

northwest within an east-west striking structural zone host quartz and calcite veins and

stockworks with siderite and hematite. The mineralized structures are enveloped by zones of

silicification and hematitic, reddish-stained, altered sedimentary rocks.

Historic reports indicate that twenty-one shallow reverse circulation holes totaling 1,126 meters

were drilled in 1996. According to the author of a 1999 report, thirteen of the holes intersected

“significant” gold mineralization (Summary Report, La Navidad – Shelly Gold Project, F.M.

Johnson, 1999). Table 1 below indicates a selection of the better historic drill results. Drilling

done to date did not completely test the target. Millrock believes there is good potential to

extend the mineralized zone and to find parallel zones at deeper levels.

Millrock cautions that these drill results are historic and have not been (and cannot be) verified

by the qualified person that is responsible for the contents of this disclosure. The results

reported in Table 1 are taken from the 1996 report written by F.M. Johnson. While it is known

that the drill samples were assayed at a well-known, reliable, laboratory (Bondar – Clegg of – at

the time – 130 Pemberton Avenue, North Vancouver, B.C. Canada V7P2R5), the Millrock

qualified person has not seen the assay certificates. No drill sample chips, rejects, or pulps were

retained by Western Mining from the 1996 drilling program and the qualified person has

therefore not viewed or resampled any of the rock drill samples that were assayed. The qualified

person has visited the project site, observed vein structures in rock outcrop and old workings

and believes that the reported drill intersections are likely to be accurate. The holes were drilled

vertically, and therefore the reported intersections are apparent thickness. True width is likely to

be approximately 65% of the reported apparent width.

Millrock has an option to purchase a 100% interest in La Navidad from Western. To complete

the purchase, US$2,500,000 in option payments to Western may be made over a four-year

period. An initial payment of US$125,000 has been made. Three further option payments of

US$125,000 each may be made at annual intervals. A final option payment of US$2,000,000

could be made to complete the purchase of the mineral rights. During the option term, at least

US$3.0 million must be spent on exploration on La Navidad in order to exercise the purchase

option. The first year commitment is US$500,000. Millrock, with Centerra concurrence, may

withdraw from the option agreement at any time.

Through its agreement with Millrock, Centerra has the option to earn an 80% interest in La

Navidad by funding the all of the financial obligations in the underlying agreement between

Millrock and Western. At vesting, a joint venture would be formed. Millrock may participate by

contributing its pro-rata share of costs, or it can elect to be diluted to a 2.0% Net Smelter Return

royalty.
